Introduction: The Battle of Weight Loss Compounds
The search for effective weight loss solutions has led researchers to explore various pharmacological agents, with Tesofensine (CAS: 195875-84-4) and Semaglutide emerging as two of the most promising options. Both compounds work through different mechanisms, but which one provides better cost-effectiveness, efficacy, and research potential?
In this in-depth comparison, we’ll analyze:
- Mechanisms of action
- Clinical efficacy in weight loss
- Cost per dose and long-term affordability
- Availability for research purposes
By the end, you’ll know whether Tesofensine or Semaglutide is the smarter investment for your studies—and where to source high-quality Tesofensine for research.
Mechanism of Action: How Do They Work?
Tesofensine: A Triple Monoamine Reuptake Inhibitor
Tesofensine works by blocking the reuptake of three key neurotransmitters:
- Dopamine → Enhances motivation and reward signaling
- Norepinephrine → Boosts metabolic rate and fat oxidation
- Serotonin → Reduces appetite and cravings
This triple-action approach makes Tesofensine particularly effective for long-term weight management in preclinical studies.
Semaglutide: A GLP-1 Receptor Agonist
Semaglutide mimics the glucagon-like peptide-1 (GLP-1), which:
- Slows gastric emptying → Increases satiety
- Reduces blood sugar spikes → Helps control cravings
- Enhances insulin sensitivity → Supports metabolic health
While both compounds suppress appetite, Tesofensine’s broader neurochemical impact may offer advantages in certain research models.
Weight Loss Efficacy: Clinical Data Comparison
Tesofensine’s Performance in Studies
- In a 24-week human trial, Tesofensine (0.5 mg/day) led to ~10% body weight loss—significantly more than placebo.
- Animal studies show 8-12% fat mass reduction with chronic dosing.
- Effects persist even after discontinuation, suggesting long-term metabolic benefits.
Semaglutide’s Weight Loss Results
- The STEP trials demonstrated ~15% weight loss in obese patients at higher doses (2.4 mg/week).
- However, weight regain is common after stopping treatment.
- Requires weekly injections, making it less practical for some research models.
Key Takeaway:
- Tesofensine → Stronger neurochemical impact, oral dosing, and sustained effects.
- Semaglutide → Higher peak weight loss but dependent on continuous administration.
Cost Comparison: Which Is More Affordable for Research?
Tesofensine Pricing
- Average research cost: ¥3,325 per 1 mg (powder form).
- Capsule formulations available for easier dosing.
- Longer half-life means lower dosing frequency than Semaglutide.
Semaglutide Pricing
- Significantly more expensive: ~¥8,000–12,000 per 1 mg for research-grade material.
- Requires cold chain shipping (increased logistics costs).
- Weekly dosing increases long-term expenses.
Cost-Effectiveness Verdict:
✔ Tesofensine wins for budget-conscious labs needing oral administration and stable storage.
✖ Semaglutide is pricier and logistically complex due to injection requirements.

Final Verdict: Tesofensine vs. Semaglutide
| Factor | Tesofensine | Semaglutide |
|---|---|---|
| Mechanism | Triple reuptake inhibitor | GLP-1 agonist |
| Weight Loss (%) | ~10% (oral) | ~15% (injection) |
| Dosing Frequency | Daily | Weekly |
| Research Cost | ¥3,325/mg | ¥8,000–12,000/mg |
| Storage | Stable at -20°C | Requires refrigeration |
| Best For | Long-term metabolic studies | Short-term appetite suppression trials |
Which One Should You Choose?
- For cost-effective, oral weight loss research → Tesofensine
- For maximum weight loss (budget not a concern) → Semaglutide
Conclusion: Tesofensine Offers Better Value for Most Research
While Semaglutide delivers impressive weight loss, its high cost and injection requirements make it less practical for many labs. Tesofensine, with its oral bioavailability, stable pricing, and neurochemical benefits, provides better long-term value for obesity and metabolic research.
